Brass 1/2 Float Valve High Pressure Tank Inlet

1/2-Inch Brass Tank Valve

The Brass 1/2 Float Valve serves as a critical mechanical regulator for maintaining water levels in storage tanks, header tanks, and toilet cisterns. This heavy-duty brass component features a high-pressure orifice designed to handle standard municipal and pumped water pressures. The assembly integrates seamlessly with standard 1/2-inch BSP pipework common in residential and commercial plumbing systems.

Built for the Job

Plumbing contractors and facility managers utilize this hardware to prevent tank overflows and ensure a consistent water supply. The robust brass body resists corrosion and dezincification, making it suitable for long-term submersion in potable water systems. Its mechanical piston action provides a positive shut-off when the water reaches the designated level, reducing the risk of wastage. The threaded lever arm allows for fine-tuning the float height to suit specific tank depths or overflow requirements.

• Installation in cold water storage tanks for residential gravity-fed systems.

• Replacement of worn inlet valves in commercial toilet cistern assemblies.

• Level control for industrial header tanks and small-scale irrigation reservoirs.

Product Highlights

Industrial Brass Construction

The primary housing consists of high-grade brass alloy to withstand constant exposure to moisture and pressure fluctuations.

Adjustable Lever Mechanism

• Threaded rod allows for precise float ball positioning.
• Replaceable piston seal ensures a watertight closure every cycle.
• Heavy-gauge metal arm prevents bending under high buoyancy forces.

Technical Specifications

What’s Included

• 1 x Brass 1/2-inch float valve body with piston

• 1 x Adjustable brass lever arm

• 1 x Backnut for tank wall securing

On-Site & Workshop Notes

• Apply PTFE tape to the male inlet thread to ensure a leak-proof connection with the supply pipe.

• Regularly inspect the internal washer for grit accumulation if the water source contains sediment.

• Verify that the float ball is compatible with the 5/16-inch or 4.5mm thread on the lever arm before installation.
